Description

An environmentally friendly waste gas treatment equipment in cement production

Technical Field

The utility model relates to the technical field of waste gas treatment, and more specifically, to environmentally friendly waste gas treatment equipment in cement production.

Background Art

In the process of cement production, the smoke generated in the cement burning process contains a large amount of dust and sulfur dioxide, which needs to be treated by an exhaust gas treatment device before it can be discharged. The existing environmentally friendly cement production exhaust gas treatment equipment usually filters the dust in the exhaust gas by setting a filter plate during use, but during the filtration process, the dust will be adsorbed on the filter plate, and it is easy to get clogged after long-term use, thereby affecting the normal filtration of dust and reducing the filtration effect; secondly, the existing environmentally friendly cement production exhaust gas treatment equipment usually sprays ammonia water through multiple nozzles to react with sulfur dioxide in the exhaust gas, thereby purifying it. During the treatment process, the exhaust gas and ammonia water are often not in sufficient contact, which makes it impossible to thoroughly filter the exhaust gas, reducing the treatment effect of the entire exhaust gas treatment equipment.
